Application-filed 'J'une 29, 1914. Serial No. 848,039.

To all "whom it may concern: Be it known that I, ELVER C. FLAnAeA a citizen of the United States, residlng at Detroit, in the county of Wayne and State This invention-relates to new anduseful improvements in horseshoe callrs, andhas I for its' principal object to provide a re movable calk to enable 'theuser tosubstitute a new call: when the old one becomes worn.

i Another object of the invention is to provide a novel means for securing the call: to the shoes to enable the same to be easily and quickly removed and inserted in place and yet which will effectively hold the said calks against movement when so desired.

A further object of the invention is to prov vide self-sharpening calkswhich willfeliminate the necessity of removing the calks from the shoe to render the same effective in biting into the surface overwhich the animal is traveling.

With these and other objects in view, the.

invention consists in the novel combination 1 and arrangement of parts -which willbe fully set forth in the following specification and accompanying drawings, in which,

Figure l is a bottomcplan view of a horse shoe constructed in accordance with this invention and showing the calks in place, Fig.

. 2 is a side view in'elevation of a horse shoe calk constructed in accordance with this in vention, Fig. 3 is a top plan view thereof, and Fig. .L is a transverse sectional view of a fragment of a shoe showing the method v e havmg a recess 1n its upper surface comof securing the calk in place. I Referring now to the'clrawings by characters of reference, the'numeral 1 designates as an entirety a horse shoe of the usual construction which comprises the usual strip of metal 2, which is bent back upon itself as at 3. Formed on the strip of metal 2 at suitable intervals are the depending enlargements 4 which are formed with the tapered slots or grooves 5 in which the calks, which will be more fully hereinafter described, are held. Suitable recesses 6 are formed in the lower surfaces of the portions 4 and are arranged to cobperate with the tapered grooves 5 in holding the calks in place. The calks which are designated generally by the numeral preferably comprise the main body portion 8 having the tapered sides 9. These sides taper toward their inner edges on which are formed the lugs 10, which are arranged to fit into apertures in the bottom of the grooves 5. Formed integral with the body 8 is the lateral extension 12 which tapers toward the'inner edge of the body 8 andisarranged to cooperate with the recess 6 in looking the call: in place.

7 It will be apparent from the foregoing that in. use the calks are placed in their respective grooves and wedged tightly there- 1n. "-The user then takes a cold chisel or similar instrument and upsetsthe free edge of the recess 6, thus firmlylocking the calk against movement.

A slightly modified form of calk is used at the heels of the shoe and in this form the inner edges of the members 8 are-beveled so that the inner edge of the shoe is left sub-- stantially smooth, thereby eliminating the danger of the horse injuring itself. 7 It is to be understood that these heel calks are interchangeable to insure even Wear.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it isto be understood that such changes may be made in the combination and arrangement. of parts as will fall within the spirit and scope of the invention as defined in the appended municating with said slot, of a horse shoe calk comprising a tapered body portion, a pair of spaced lugs formed at one edge of the tapered body portion, and a tapering extension adapted to be held in the tapered slot in the enlargement whereby the body portion is held in place.

2. The combination with a horse shoe comprising a body portion, a plurality of spaced enlargements on the body portion,

each of said enlargements being provided with a transverse tapering'slot and having a recess communicating therewith, of a horse shoe calk comprisinga tapering body por-v .tion, a pair of spaced lugs formed on one edge of the body portion, a tapered extension formed on the body portion, said tapered extension being adapted to enter the tapered slot, and a lateral projection formed on the body portion and arranged to enter the recesses formed in the enlargements and thereby lock the calks firmly in place.

8. The combination with a horse-shoe comprising a body portion, of a plurality of spaced enlargements formed on the body portion, each of said enlargements being provided with a tapered transverse slot and having arecess in its upper surface communicating with said slot, of a horse-shoe calk comprising a fiat tapered body portion, a tapering extension formed on the body portion adapted to be held in the tapered slot in the enlargement and means for holding the calk in place.

4;. A horse-shoe comprising a body por- Gopies of this patent may be obtained for tion formed with a boss having a slot which is tapered toward its bottom extending transversely of the body, said slot being formed with a lateral recess intermediate the ends of the slot in one wall thereof, which recess is tapered toward the bottom of the slot, and

a calk to fit within the slot comprising a blade portion and a shank portion, the shank portion being formed with a rib at one side to fit the recess and tapered to fit the slot,
